Abstract (en)
A method and apparatus for a co-scheduler can mitigate UE-to-UE adjacent carrier frequency band interference by allocating three sets to a first user equipment uplink. Each set has at least one sub-carrier in a first frequency band, at least one uplink time period, and at least one transmission power parameter. The co-scheduler initially allocates the first set. The co-scheduler allocates the second set in response to detecting a second user equipment operating proximal to the first user equipment, and the second set differs from the first set in either at least one sub-carrier or at least one transmission power parameter. The co-scheduler allocates the third set in response to detecting that the second user equipment is no longer operating proximal to the first user equipment, and the third set differs from the second set in either at least one sub-carrier or at least one transmission power parameter. Various methods for controlling an aggressor user equipment (UE) can use two transmission power control loops to mitigate UE-to-UE adjacent carrier frequency band interference to a geographically proximal victim UE. The aggressor UE can select between different transmission power parameters based on two (or more) power values. The usage of any particular power value depends on the time period of the transmission. For example, if a proximal victim UE is scheduled to receive when the aggressor UE is scheduled to transmit, a lower power value may be selected as instructed by a co-scheduler or determined by the aggressor UE. The aggressor UE can also send dual power headroom reports to its serving base station based on the two power values.
